The addition of iso-octane extends the knocking limit in equivalence ratio somewhat, however the knock occurrence mainly depends on the total concentration of mixture. Although the operation range in equivalence ratio becomes narrow with the increasing of iso-octane, the maximum load is improved 80% by n-heptane/iso-octane controlled real-time in contrast with the HCCI fueled with n-heptane only.
结果表明:混合燃料HCCI着火以及燃烧相位主要取决于正庚烷实际的燃空当量比;异辛烷的加入对爆震当量比界限有所拓展,但HCCI爆震主要与混合燃料总当量比有关;随着辛烷值比例的提高,导致HCCI运行范围变窄,但是实时调控证明相对纯正庚烷,混合燃料的HCCI燃烧最大负荷提高了80%。
